CHAPTER 8 DECIMALS
TENTHS
When one block is divided into 10 equal parts, each part is one-tenth of the whole.
E.g. 5.6 means 5 wholw parts and 6 parts of the 10 parts of the whole.
HUNDREDTHS
When one block is divided into hundred into 100 equal parts, each part is one hundredth of the whole. E.g. 25.25 means 25 whole parts and 25 parts of the 100 parts of the whole.
COMPARISON OF DECIMALS
The comparison is started from the whole part. If the whole part is equal, we compare the tenths part and so on.
ADDITION OF DECIMALS
Addition is done the same way whole numbers are added. E.g. 5.67+3.1= 8.77
SUBTRACTION OF DECIMALS
Subtraction is also donate same way whole numbers are subtracted. E.g. 5.67-3.1= 2.57
